There is a widespread perception that conducting business on the Internet has a higher risk than in the traditional face-to-face environment. This is due, in part, to security concerns and to the need for an extra level of trust incurred when paying for goods or services before receiving them. For the majority of consumers, the benefits of immediate access and search capabilities, as well as 24-hour access to businesses on a global scale, outweigh many of these security and trust concerns. Nonetheless, a healthy skepticism of some Web sites, and to deals offered, is essential because for a few people the Internet provides an easy means of concealing illegal and malicious activities. While there is a common perception that the security of Internet-based transactions is weak, the reality is otherwise. Current security techniques are much stronger than techniques used when conducting transactions via fax or over the telephone. Nonetheless, although the perception of vulnerability is stronger than the reality, digital threats do need to be taken seriously. If an Internet organization is to survive and prosper, it must be fully aware of the threats and attacks (both internal and external) that can be used against it. Both businesses and government agencies operating electronically need to be vigilant against information theft, espionage and liability. They need to establish as many deterrents, defenses, and security measures as necessary, to protect their systems and data, and to understand the principles behind these to counter new threats. Further, the digital business needs to establish an ongoing maintenance program, and good administrative practices, to ensure security measures are kept up to date. [Book Synopsis]
